snowflake-validation

snowflake-validation is a skill for Claude Code from ulises-jeremias/agent-toolkit. It costs 36 tokens per session (404 once invoked), scanned A, original, MIT.

A set of read-only checks for validating Snowflake, a cloud data warehouse, using the commands and SQL documented by a repository.

In plain words
What is it for?
Use it to run documented Snowflake smoke queries, record validation evidence, or explain what could not be checked when access is unavailable.
Why use it?
It prevents agents from claiming that a database check passed without valid credentials and observed results, and helps avoid accidental changes to data or security settings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

snowflake-validation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Snowflake validation (HOW)

Use when the task or repo requires Snowflake verification. Client workflows may delegate here alongside dbt-validation.

Boundaries

  • Read-only validation unless the user and repo explicitly authorize DDL/DML.
  • Never claim “Snowflake validation passed” or “query succeeded” without credentials and observed outputs (or explicit statement that checks were skipped).
  • Do not rotate keys, change roles, or alter security objects from this skill unless the repo’s AGENTS.md clearly authorizes it and the user approves.

Discovery

Read repo docs for: connection method (env vars, profiles.yml, SSO), Snowflake SQL or Snowflake CLI (snow) usage, and warehouse/database/schema defaults.

Patterns

Situation Action
Credentials available Run minimal SELECT statements or documented smoke queries; record that they were executed
Snowflake CLI documented Use repo’s exact commands; check snow --help for current subcommands
No credentials State skipped in Jira/PR; list what would be validated when access exists
dbt + Snowflake Coordinate with dbt-validation; Snowflake may be exercised indirectly via dbt

Evidence

  • For each run: what ran (object or test name), environment (non-secret), result (row count, success/failure).
  • Redact account identifiers if the user requests privacy in chat.

Safety

  • No secrets in tickets, PRs, or command lines in logs pasted to chat—use env vars and documented patterns only.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
